A $100 hamburger trip typically involves flying a short distance (less than two hours), eating at an airportrestaurant, and flying home. "$100" originally referred to the approximate cost of renting or operating a light general aviation aircraft, such as a Cessna 172, for the time it took to fly round-trip to a nearby airport. However, increasing fuel prices have since caused an increase in hourly operating costs for most airplanes, and a Cessna 172 now costs US$95–130 per Hobbs hour to rent, including fuel.[3]
